Herpes labialis is caused by which virus?

Explanation:
Herpes labialis is caused by herpes simplex virus type 1. This virus commonly infects the oral area and produces the familiar cold sores around the lips. It lies dormant in the trigeminal ganglion and can reactivate, especially with stress or illness, causing recurrent lesions. The other viruses listed have different disease patterns: human papillomavirus causes warts and certain cancers, rhinovirus causes the common cold, and varicella-zoster virus causes chickenpox and shingles. HSV-1 is the classic cause of oral herpes, though HSV-2 can rarely affect the oral area.
